Abstract
The utility model discloses a kind of photoelectricity mixing tight tube fiber, comprise optical fiber and wire, optical fiber is coated with optical fiber tight sleeve layer, wire is coated with wire tight sleeve layer, described optical fiber tight sleeve layer is connected with wire tight sleeve layer Local Phase, and between the two formed be convenient to be separated easily tear portion; Optical fiber in the utility model and wire are tight tube structure; optical fiber is used for the light signal of transport communication; wire is used for transmission of electric signals; formed between optical fiber tight sleeve layer and wire tight sleeve layer and easily tear portion; use can be torn as required; in addition because wire has certain intensity, the effect of protection optical fiber can be played.
Description
Technical field
The utility model relates to a kind of tight tube fiber.
Background technology
As the elementary cell in indoor flexible optical cable structure; tight tube fiber structure is widely used; the basic structure of tradition tight tube fiber is outside optical fiber, the tight sleeve layer that the macromolecular materials such as extrusion molding one deck fire retardant polyolefin or flame-proof polyvinyl chloride are formed, and tight sleeve layer is that optical fiber provides the most basic protection.But the tight tube fiber of this quasi-tradition only can carry out the light signal for transport communication, cannot transmission of electric signals.
Summary of the invention
The utility model object is: provide a kind of photoelectricity mixing tight tube fiber; its optical fiber and wire are tight tube structure; optical fiber is used for the light signal of transport communication; wire is used for transmission of electric signals; formed between optical fiber tight sleeve layer and wire tight sleeve layer and easily tear portion; use can be torn as required, in addition because wire has certain intensity, the effect of protection optical fiber can be played.
The technical solution of the utility model is: a kind of photoelectricity mixing tight tube fiber, comprise optical fiber and be coated on the optical fiber tight sleeve layer on optical fiber, also comprise wire, wire is coated with wire tight sleeve layer, described optical fiber tight sleeve layer is connected with wire tight sleeve layer Local Phase, and between the two formed be convenient to be separated easily tear portion.
Further, described wire is one or two, when it is two, and, two wires are coated with wire tight sleeve layer respectively, and two wire tight sleeve layers and optical fiber tight sleeve layer are that triangular shape is arranged, three is interconnected in the center of this triangle and forms and easily tears portion.
Further, the optical fiber in described optical fiber tight sleeve layer is one or more.
Further, the material of described optical fiber tight sleeve layer and wire tight sleeve layer is consistent, adopts low smoke halogen-free flame-retardant polyolefin (LSZH), polyurethane (TPU) or polyvinyl chloride (PVC) material to make.
The utility model has the advantages that: the optical fiber in the utility model and wire are tight tube structure; optical fiber is used for the light signal of transport communication; wire is used for transmission of electric signals; formed between optical fiber tight sleeve layer and wire tight sleeve layer and easily tear portion; use can be torn as required; in addition because wire has certain intensity, the effect of protection optical fiber can be played.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is the schematic cross-section of a kind of execution mode of the utility model;
Fig. 2 is the schematic cross-section of the another kind of execution mode of the utility model.
Wherein: 1 optical fiber; 2 optical fiber tight sleeve layers; 3 wires; 4 wire tight sleeve layers; 5 easily tear portion.
Embodiment
Embodiment one: as shown in Figure 1, a kind of photoelectricity mixing tight tube fiber, comprise optical fiber 1 and a wire 3, described optical fiber 1 is coated with optical fiber tight sleeve layer 2, wire 3 is coated with wire tight sleeve layer 4, described optical fiber tight sleeve layer 2 is connected with wire tight sleeve layer 4 Local Phase, and forms the portion of easily tearing 5 being convenient to be separated between the two.
Embodiment two: as shown in Figure 2, a kind of photoelectricity mixing tight tube fiber, comprise optical fiber 1 and two wires 3, described optical fiber 1 is coated with optical fiber tight sleeve layer 2, each wire 3 is coated with wire tight sleeve layer 4 respectively, two wire tight sleeve layers 4 are arranged in triangular shape with optical fiber tight sleeve layer 2, and three is interconnected in the center of this triangle and forms the portion of easily tearing 5 being convenient to be separated.
In above-mentioned two embodiments, the optical fiber 1 in described optical fiber tight sleeve layer 2 can be one or more, i.e. single core or multicore.The material of described optical fiber tight sleeve layer 2 and wire tight sleeve layer 4 is consistent, and low smoke halogen-free flame-retardant polyolefin (LSZH), polyurethane (TPU) or polyvinyl chloride (PVC) material can be adopted to make.The material of wire 3 can be the material of all conductions such as copper, aluminium.
Optical fiber 1 in the utility model and wire 3 are tight tube structure; optical fiber 1 is for the light signal of transport communication; wire 3 is for transmission of electric signals; formed between optical fiber tight sleeve layer 2 and wire tight sleeve layer 4 and easily tear portion 5; use can be torn as required; in addition because wire has certain intensity, the effect of protection optical fiber can be played.
Below be only embody rule example of the present utility model, protection range of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other execution mode.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
